Youre a life saver. Seriously, I really cant thank you enough. You have literally saved me. You dont know how much it means to us students. Thanksssss

2.71 million subs aren't enough...I passed both AP and honors chemistry, Algebra 1,2 and 3 enhanced, and AP calculus just by watching your videos. Not to mention, I also show the Investment Club I lead your investment and stock videos as well. Thank you so much, God Bless.

2 years later, he has the same numbers just in a different order. At 7.21m subs now!

I hope a math formula invented in the future is named after this guy to instill his helpfulness for all of time.

Just wanted to say thank you, you are a serious life savor. I usually use your videos as a brush up on what we learned in class, bc I suck at math, and now with online classes and the whole pandemic, I have found myself even more confused and I feel lucky that I knew where to turn too (bc our school has bad tutors too). Thank you so much for your videos!

This guy is mysterious, but a god at what he does. Who is you? Mr The organic chemistry.

I AM BUT THE APPRENTICE

Thank you for helping me to pass high school and univeristy. You're a life saver, thank you.

You’re videos are excellent because you explain and cover all the materials perfectly! Thank u very much!

Much Love from Africa,you are really helpful sir.

In the class they don't teach us like that.. Thanks, it helped me a lot.

You are the best teacher - best on KZread. I learn a lot from all your videos. Thank you so much. Please post more AP Calculus and AP Chemistry videos. Please post AP Calculus videos with solved college board questions. Thank you.

I really enjoyed watching your videos. Very explanatory and understandable.

I understand you better than my teacher, thanks so much for making this videos they have helped me a lot

I wish people could donate; this guy is very calm and helpful.

you the best teacher i have ever come across online . you are so smart

SUPER CLEAR! I LOVE THIS! please, keep up with the videos you are a life saver!

from the bottom of my heart, thank you so much for these videos

This guy's videos helped tons of people!

you're the only reason I'm passing calc thanks for your videos

I got full mark in the exam...I do not even practice my Textbook queries as once I watch your video everything is explained well..your are extremely good in explanation..pliz update more and more videos..

Just wanna say you are amazing teacher....You solved mah biggest problem....you are just outstanding...

you are really a great person thank you so much for shearing your knwledge because knowledge is freedoom

This was really helpful, Thanks a lot.

This guy is a life saver 🙏🏾

Excellent, as always.

Thanks ❤. please do videos on area between two curves and also on volume by slicing disks and washers methods ,volume by cylindrical shells

OK. You corrected it. I was wondering why no one mentioned it earlier.

I really like all your videos. They are the best on youtube, in my opinion. But my attention span litterally ends in like 6 mins or so when I watch ur videos.. like, I struggle to stay focused. 😁. But anyways, awesome vids! Keep it up! 😎

Thank you so much for everything 💕

Very useful. Thank you sir.

Cursseeee you, that tutor guyyyyyyyy!!!!!!!!!

Thank you !

THANK U BROTHA

Seriously I Thank u.

Very helpful

awesome, now do it with trig max and minimums !!

41:33, I am confused why 0 is part of the critical points. Wouldnt it just be -1 and 1?

you are amazing

I have a query. at 3:58 we have a graph which does not have a minima as last point is encircled and therefore is not part of the graph but the point before that is included in the graph so why we don't consider it as a minima. Thanks in advance

I am a normal student,I see this dude's video,I like

Thank you

youre the best!

14:08 you said if the leading coefficient has a odd power like x^3 then it will have no max or minimums. but at 22:21 that function also has a leading coefficient with odd power of ^3 but that one has a max and minimum for some reason?

For the last problem I dont think you would include -3/2^1/2 because it is equal to -2.1 which is outside the restricted domain. so there would be no local min and -2 would be the absolute min. Correct me if Im wrong.

At 1:09:00 he said it’s not part of the interval

@36.12 it should be minus 12(0) i.e -0 and not +0 as stated in the question but more importantly perhaps @ 3.27 which should be -12(2) and not +12(2) ...... -24 and not +24 hence final answer @36.45 should be -7 and not +41.

Thanks 👍

@1:04:30 you keep using -3/sqrt(2) wich is -2.12 so its out of our intervall. Or did I do something wrong here?

@misutokiriya6547

It's been like a year but for future uses, he did remove it in the end; thus, not making it the absolute minimum value in the interval [-2,3]

how is 5/3 present in 2/3? please explain

So like... does chain rule not apply to this because when you bring the exponent down don't you have to multiply the expression by its derivative-

Quick question: Wouldn't the square root of 9-(3)^2=0, which would create a domain issue?

Thank you for this video, nice explanations. One correction: f(2) = 3(2)^2 - 12(2) + 5 = -7 actually, not 41. Cheers!

Whoops, just saw your in-video correction. No worries!

on 57:26, shouldn't the graph be restricted on the interval [-1,2]? Why did you make it continuous on all real numbers?

This video has saved me in my darkest hour

Thanks G

what will we do when we have modulus function

Thanx

What if we have two minimums, but they are "the same"? (-1, -1) and (1, -1). Are both absolute minimum? Or are they both local minimum?

52:10 If you want to shave (valuable) seconds off (while getting a better idea visually/kinestheticly), don't bother wasting time "testing points" to find out where the derivative changes sign. Simply quickly plot the (*numerator of the) derivative, ie plot f' vs x. Just use end behavior and the zeros to do this. (*Yes, there is something in the denominator in this particular example because we are dealing with a rational function, but in this example the denominator is always positive, so it won't affect finding where f' changes sign. Keep in mind, that you can avoid "testing the points" 100% of the time if dealing with a polynomial function.)

thank u

Very nice but on 7:20 you said if f'(c) doesn't exist, we have a cusp. Not necessarily coz we might have vertical tangent just like in f(x)=x^(1/3) at x=0 . So how can we tell if we have a cusp or vertical tangent?

@SM-qn7sr

2 жыл бұрын

its a cusp because if f'(c) doesnt exist at x=a certain number then its not differentiable at that number and not differentiable means the first derivative isn't continuous on x=that number. Its only a verticle tangent if f(x) is undefined, not f'(c)

God bless you

52:25 if you plug in 1 the answer is gonna be negative no ?

In 27:55 it's super complicated.

8:82 Shouldn't the lower local min be a critical number instead?

57:50

whoever dislikes his videos will never be able to learn anything in life.

Please, do you have to find the X and Y intercepts to draw the graph with accuracy? If so, then how do I find my X_intercept for 2x^4 - 2x^2 - 1=0? Thank you

It doesn't look factorable. You can use the quadratic formula where a = 2, b = -2, and c =-1. The result that you get will equal x^2 and not x so you will have to take the square root of that result to get the final answer. You can also graph it using an online graphing calculator and find where it touches the x axis. Go to google and type in 'online graphing calculator' and the choose the first link that comes up which is desmos.com. Type in the expression "2x^4-2x^2-1" without the =0 part and you should see the graph. Move the mouse to the point where the graph touches the x - axis and you should see the answer. x = +1.169 and -1.169. I hope that helps :)

Hi, for the first problem you did, does it matter which number you plug into the first derivative? You did plugged in a # that is smaller than 1.5 into 2(2x-3). If I plug in a # that is smaller that 1.5 into 6x-6, would I still get the same answer as you? Thank you!
